Protect Your Home From Dry Rot!
The Bad News
- While dry rot is not the most common type of wood rot in Davenport, it can deal serious damage to your home and endure conditions that are too dry for other types of rot to thrive. In fact, up to a 75% loss in the toughness of the wood is possible with just a 1% decrease in the wood's weight of the wood.
- Dry rot fungus spores are present in most homes and can survive for several years, waiting for the right conditions to grow.
- Dry rot can pull moisture from moist areas to dry areas. It grows through mortar, concrete, masonry, and behind plaster.
The Good News
- Despite its name, dry rot needs moisture to produce spores-- at least 28-30% moisture content within the wood with a relative humidity of 95% or higher. Most softwood timbers in dry homes, especially in the upper levels, have a moisture content of 12-15%.
- Dry rot problems in basements and crawl spaces can easily be solved by controlling moisture by sealing and dehumidifying the space.
- Treatment of the wood products such as boric acid is known to eliminate and prevent dry root fungi.
What is Dry Rot & Brown Rot?
Dry rot is a term typically used to describe a certain kind of cracking, rotting wood, and is caused by a variety of fungus, most notably Serpula Lacrymans. Despite the name, dry rot needs moisture in order to grow and produce spores (at least 28-30% moisture in the wood with a relative humidity of 95% or higher). Because it technically needs moisture, many people now call this phenomenon “brown rot” instead of dry rot.
Dry rot (also known as brown rot) is one of the most damaging forces on household wood in the world.
Identifying & Treating Dry Rot or Brown Rot Problems in Illinois and Iowa
Typically, dry rot first appears as a reddish dust, which is actually an accumulation of fungal spores. Outbreaks of dry rot often occur a few months following a household flood event such as a burst pipe or failed water heater. Dry rot is common in basements and crawl spaces, and is often not detected until significant damage is underway. MidAmerica Basement Systems recommends the following steps for fixing dry rot:
- Remove all visibly damaged wood and wood within 1 meter of it
- Remove other nearby materials, such as drywall, plaster, linings, and ceilings
- Wire brush clean affected area, including pipes and masonry, and remove all dust and debris
- Disinfect all wood, masonry, and materials within 1.5 meters of affected area
- Rebuild using new, pressure-treated wood
- Prevent future damage by installing vapor barriers and dehumidifiers, where applicable
Damage from dry rot creates small, rectangular pieces of crumbling wood on the surface. Dry rot damage is often mistaken as a termite infestation.
All wood that shows decay or visible fungus should be removed, as well as all wood within one meter of the visible decayed material.
Plaster, paneling, linings, and ceilings around the dry rot areas can also contribute to the damage and should also be removed.
Using a wire brush, loose material is removed from all surfaces within 1.5 meters of the furthest edge of the infestation, including metal, masonry, and pipes. Resulting dust and debris is removed as well.
A disinfectant is applied to all wood, masonry, and exposed soil in within 1.5 meters from the damage.
Substantially rot-damaged beams, joists, and posts are replaced with pressure-treated wood.
Remove all standing water sources, then install a plastic vapor barrier on the walls and floors. Install a self-draining dehumidifier powerful enough to dry the area. (At least a 100-liter model)
Seal off all crawl space vents and door covers. Encapsulate the crawl space with a crawl space liner, then install a self-draining crawl space dehumidifier.
Dry Rot Alert!
Architect's Journal reports that dry rot can grow through damp mortar, concrete, masonry and behind plaster.
This makes remediation of dry rot complicated and expensive, and it can lead to future problems with dry rot if it is not treated properly.
